and which may be grouped in anydes'ired arrangement, the valve stems'bein'g shown at 11, 11a, 11b, and 110.

For the purpose of selectively operating the several valve members l we provide a selecting device having parts adapted to be moved transversely to the length'of the valve stems 11 into and out of alineinent with Means are'alsoprovided' for imparting movementto thisselecting device in the direction of the length of the valve stems so that thoseparts thereof which have been moved into line withvalve stems vill engage those valve stems and actuate the same with a straight axial thrust. In the present construction a stud 14 is rigidly secured to the valve casing and it projects upwardly therefromto a point some distance stems, this stud being'in the present instance arranged centrally of therasing. V The valve casing is provided with a recess 15" in the" upper part thereof which surrounds the stud ll. The selecting device is here shown as a disk-like memberlG and isslidably and rotatably mounted upon the stud 1 1. Preferably it is provided with a dependingbearing portion or hub 17, the lower end of which extends into the recess 15 in the casing. A. spring 18 is confined between the casing and the disk-like member 16 and tends to hold the latter normally in its elevated position.- The actuating device further comprises a pinrality of parts which depend from the disklike member .16 and are soarranged with relation thereto that they maybe moved into and out of line with selectedvalve stems. These projections may beof any suitable character and, in the present instance, we have utilizedtwo forms ofprojections. In

one instancelugs 19 are formed integral with the disk-lilte member 16. In the other instance the projection is inthe form of a screw '20 threaded through the member 16 and locked in position thereon by a. nut'21. In

1 thismannerthe projection made adjustable "with relation to the disk-like 7 member 16,

thereby enabling the amount'of movement imparted to the valve stem by a given moveinent of the' 'selecting device to be varied so as to cause the-valves to be opened different distances. y The multiple valve here illustrated is designed primarily for use on a bakelite press and. in" the operation of such a press the bakelite or material to be molded is first" placed in the mold and the mold closed, then the steam is circulated about the mold to heat the same while pressure is being applied, thereto. After the moldmg operation'is completed the steamis shut off and cold water c1r-,-

culated about the mold to cool the same. The

steam inlet isthen connected with 'themold and the mold is connected with the drain so as to discharge the water therefrom. The

inlets and outlets for the steam and water are all arranged withinthe single valve casing erating mechanism the projections on .the

selecting device are-so arranged that when the selecting device is rotated to any one of'three predetermined positions two of the lugs or projections thereon will be in line with the stems of the valve members which are to be operated.

Any suitable means maybe provided for depressing the selecting device to cause the projections-to engage the valve stems with which they arein line and to impart axial movement thereto. Preferably a single handle serves both to'r'otate the selectingdevice and to impart'axial movement thereto thus enabling the selecting device to be very quickly positioned and actuated.

In the particular construction here illustrated the selecting member'or disk 16 has on its upper surface two bearings 22 arranged on opposite sides of the stud 15,-these bear ings being preferably formed integral with the member 16. Journaled in the respective trunnions 23', the inner ends of which extend inwardly beyond the respective bearings and are flattened on one side as shown at 2 -These inwardly extending portions of the 13111111110118 P1018017 beneath a shoulder carried by the lixed stud 14 and which, in the present instance, comprises a collar mounted on the stud and held in posi- V bearings 22 are two cylindrical members or i will engage the collar 25 and acting against the same will force the selecting device 16 downwardly, the throw of the cams being sufficient to impart the desired movement to the valve stems. The trunnions' are pref erably actuated by a handle 27, the-lower portion of which is bifurcated and the respective arms 28 thereof rigidly secured to the outer ends of the respective trunnions. In the pres ent device each arm of the handle is provided on opposite sides of its axis with inwardly extending parts, 29 forming'between them a longitudinal slot and each trunnionhas at its outer end an outwardly extending lug 30,

which enters the slotfin thei corresponding 7 ,arm, the lugs'a'nd the'slots being so shaped as to hold the parts against relative rotation. Screws 31 serve to hold the'arms of the handle against displacement with :relation to the trunnions. "The shape of the cam portions 24 ofthe trunnions is suchthat axial movement may be imparted to the selecting device by i the movement'of thehandlein either direcas it is desired to operate the selecting device by: the-'rnovementof the ha-ndle in one direc-f v 'What we claim asne'w-and"deslre to secure'hy tion'onlyfwe have provided the armsfl28 of the handle' with stops 32 arranged'tojengage the disk 16 andprevent the movementiofthe handle in'one direction about this transverse 7 axis.

It will be apparent that by grasping the whandle smearotating the same about the V vertical axis of'the selecting device that the device may be moved to the desired position and'hy then exerting a forward pull on the handle QY the selecting device is depressed to' actuate the valve members.
